Title: Color difference signal inverting circuit
Inventor: TANAKA SEIICHI
IPC: H04N9/74
Filed: 1988-08-19
Abstract: PURPOSE:To avoid a colored achromatic part or noninversion of part of a picture by discriminating the polarity of a digitized color difference signal and converting the color difference signal into 2's complement when the polarity is positive and converting the signal into l's complement when negative. CONSTITUTION:A level inverting section comprising an inverter circuit 25, an adder circuit 26 and a data selector 27 discriminate the polarity according to the value of the most significant bit of color difference signals R-Y, B-Y. When the polarity is positive, the color difference signals R-Y, B-Y are converted into 2's complement and when negative the color difference signals R-Y, B-Y are converted into 1's complement for the level conversion. Thus, the positive number is converted into a negative number with the same absolute value, 0 is converted into 0 and a negative number is converted into a positive number whose absolute value is less by 1. Since 0 is converted into 0, the achromatic part remains achromatic. Moreover, the negative maximum value is inverted into a positive maximum value and any sample is inverted without fail.

Abstract: PURPOSE:To facilitate the manufacture of the title device and make it possible to promptly cope with a variation in the shape into which a plate is to be bent, by rolling a roller in the direction of a tip part of an anvil while pressing the roller against a machine plate supported on an upper surface of the anvil, thereby driving the roller into the tip edge of the anvil, and thereby rolling the roller along the lower surface of the anvil in the direction of a base end part. CONSTITUTION:A machine plate (w) is fixed to a from bed 21, and arms 26, 27 are turned upward with rollers 29, 30 positioned on the tip side of the arms 26, 27, whereby the rollers 29, 30 are moved toward the base side of the arms 26, 27, and are moved to the upper side of anvils 23, 24. Then, the arms 26, 27 are turned downward to press the rollers 29, 30 against the machine plate (w), and the rollers 29, 30 are moved toward tip parts of the arms 26, 27, and are driven into tip edges of the anvils 23, 24. Thereafter, the rollers 29, 30 are moved toward the base parts of the arms 26, 27, and are rolled toward the base parts while pressing the machine plate (w) against lower surfaces of the anvils 23, 24. By this, the machine plate (w) is brought into perfect close contact with the anvils 23, 24, and can be bent along the anvils 23, 24 with high accuracy.

Abstract: PURPOSE: To accurately identify the kind of the surface flaw of an object to be inspected while performing the discrimination of acceptance or rejection and re-inspection not only to reduce the number of visual inspectors but also to feed back inspection data to a manufacturing process. CONSTITUTION: The image of the detection area 1 on the surface of a photosensitive drum 2 is read by a CCD camera 6 and subjected to signal rocessing in a signal processing part 8 to be inputted to a flaw judging part 9.

Title: Capacitor and formation thereof
Inventor: TARUI YASUO
IPC: H01L27/04
Filed: 1993-08-20
Abstract: PURPOSE:To realize a capacitor in which the leak current is reduced significantly regardless of the material of lower electrode by additionally providing a step for annealing a dielectric thin film and a lower electrode structure in active oxygen atmosphere after implanting an appropriate quantity of elemental Si ions into them. CONSTITUTION:A lower electrode material Mo is deposited on an Si substrate 1 on which SiO2 has been grown through thermal oxide and then it is patterned by photolithography. The Si substrate 1, on which an Mo lower electrode 2 is formed, is then cleaned and dried and Ta2O5, is deposited entirely on the substrate including the Mo electrode 2. Subsequently, Si ions are implanted into the Ta2O5, which is thereby subjected to active oxygen annealing. When a dielectric film 3 is deposited on the Si film, amorphous Si film is partially converted into a thin oxide and the remainder is taken, in the form of elemental Si atoms, into nearby Ta2O5. When annealing is effected under that state, Si is diffused outward toward the surface of a dielectric.

Title: Driving force transmission
Inventor: INUI MASAKI
IPC: F16D43/284
Filed: 1989-08-09
Abstract: PURPOSE:To eliminate the highly frictional state of a friction clutch to seize it and prevent burning and any other damage by urging a piston by a pushing member, wherein a temperature sensing member is used, to cut off the intercommunication between a fluid chamber and a cylinder by the piston. CONSTITUTION:An annular second piston 18a is liquid-tightly and slidably inserted into a cylinder part 13d. The second piston 18a is urged by a plate spring 18 interposed between a support plate 13a and the second piston 18a to be seated at the bottom of the cylinder 13d, thereby cutting off the intercommunication between a fluid chamber and the cylinder 13d under a predetermined pressure. The plate spring 18b is made of bimetal or shape memory alloy, and is deformed into a flat shape at a preset high temperature to dissipate the pressure with respect to the second piston 18a and remarkably reduce the pressure of an operating piston 13 with respect to a friction clutch 10b. Therefore, the highly frictional state of the friction clutch 10b is eliminated to be burnt so that no other damage cannot be generated.

Inventor: TETSUYA SHINJI
IPC: G06F21/31
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To discriminate the communication terminals without using plural different user IDs, password numbers, etc., by adding a discrimination ID to a user ID when an access is carried out via a 1st terminal and using only a user ID when an access is carried out via a 2nd terminal. SOLUTION: A member 11 who is previously registered at an information management center 1 acquires a navigation CD-ROM to receive the services of the center 1 and also decides a user ID and a password number. When a navigation device 8 sends a message to the center 1, the user ID and password number are authenticated by an authentication server 3 via an access server 2 of the center 1. When the member 11 accesses the center 1 via a personal computer 9, he starts a personal computer CD-ROM to input the same user ID and password number as those which are used by the device 8. Then a discrimination ID is automatically added to the user ID of the personal computer CD-ROM.

IPC: H02G9/06
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain a protective tube by which a tube body can be inserted easily into a master tube, by a method wherein the top part of every protruding wavy shape of a tube wall is formed to be a nearly flat face, and the length in the direction of its tube axis of every protruding wavy shape is constituted to be longer than the length, in the direction of the tube axis, which is formed of the bottom part of a recessed wavy shape and of wall parts on both sides of it. SOLUTION: A tube body (p) is a tube body in which a tube wall 1 is formed to be annular recessed and protruding wavy shapes in the direction of its tube axis. The top part of every protruding wavy shape part is formed to be a flat face 2 along the direction of the tube axis. The ratio of the length L in the direction of the tube axis of every flat face 2 to the sum l of lengths in the direction of the tube axis of every bottom part 3 and of wall parts 4, 5 on both sides is set at L>l. Then, a plurality of tube devices (p) are inserted into the inside of a large-diameter tube (a master-conduit formation tube) which is buried in the ground. At this time, the tube bodies (p) are inserted sequentially into the upper-part space of an already inserted tube body while they come into contact with the already inserted tube body.  However, since the ratio is set at L>l, recessed parts and protruding parts are being engaged although the tube bodies whose tube walls are formed to be the recessed and protruding wavy shapes are used. Their relative movement is not obstructed. As a result, the tube body (p) can be inserted smoothly and quickly.
